WELCOME TO THE WONDERFUL WORLD OF TERRIERS!
He stands there at attention, a good two to three feet below your waist, totally undaunted by his small stature, totally focused, alert, and expectant as he gazes up at you with those amazingly intelligent, yet soulful, brown eyes.He may as well be talking to you "Okay, Mom, what's next?" He'll think a moment, tilt his head in acknowledgment and away you'll both go on to the next task.
Sound bizarre? Or maybe a just little off-the-wall? To some, perhaps, but certainly not to anyone who has ever shared their life with a Jack Russell Terrier. To them, it's just another day as usual with the best companion a human could ask for. The bond you've forged together didn't happen overnight. It took time, patience, and a growing sense of mutual respect. In fact, your journey together continues to be a learning experience, and that's what makes it so interesting and challenging. You continue to discover new things about each other every day, almost like an old married couple. It's a good feeling. It's a relationship that has become comfortable but never dull, secure but never without its exasperating moments, and you can't imagine life without it.

Is the Jack Russell Terrier the right dog for you?
The word terrier comes from the Latin word terra, which means "earth." Because of his unique ability to go to ground, the terrier was also called an "earthdog."
To appreciate andunderstand the modern Jack Russell Terrier temperament, it is essential to bear in mind that he was originally bred to be fearless, alert, tireless, and aggressive in the chase. The dog that has evolved into today's house pet still retains these traits, which when properly channeled, make him an extremely loyal, protective, and lively companion.
The JRT is his own "person" -a true and independent spirit capable of living life to the fullest, with joy, exuberance, and a zest few canines can match. When he and his human master function as a team, the bond between them is a privilege. But like all good things, it takes time, patience, and a lot of love to get there. Once you do, you won't find a better life companion than your Jack!
